Under the Higher Education Opportunity Program (HEOP) of the New York State Education Department, inmates of correctional facilities have been able to enroll in courses leading to postsecondary degrees at accredited institutions. In cooperation with colleges having resident HEOP programs, New York State prisons implement (1) in-prison programs under which instructors teach courses at the prisons and (2) educational release programs under which inmates attend classes at college campuses but return to the correctional facility every day. To evaluate the program, data were collected on 277 male former inmates who participated in the program and had since been released from prison. Information collected included the subjects' individual and demographic characteristics; criminal experiences; time spent, credits earned, courses taken, services received, and academic achievement in the program; and subsequent crime record, employment, income, and educational status after release. The data indicated positive program results despite short periods of participation; over half of the subjects attended college and 75 percent had been employed after release, and the group's recidivism rate was comparatively low. The report presents several tables of data and extensive descriptions of instruments used, data collection, data processing, and the variables examined in the study. (MJL)
